Abstract

In oil and gas industry activities, the oil and gas processing process will produce waste, one of which is oil solid waste, which is waste that comes from the production and processing process of petroleum in the oil field because it is one of the supports for the Cepu refinery which has several old wells that are still actively producing to this day, thus the use of waste oil is very necessary. With the amount of TPH obtained from waste oil, which is 48.10%, there is potential to be extracted. The method used is a simple heating method to separate hydrocarbons from waste solids. After the extraction test was carried out and associated with the results of the oil composition test, the saturated composition was obtained 48.84%, aromatic 23.59%, resin 25.91% and asphaltene 1.66% where this composition has an influence on the results of the hydrocarbon extraction test from waste oil. With simple heating using an oven, the results obtained are not significant as the extracted oil hardens again. After heating, the light fraction of saturated oil is released while the heavy fraction, resin and aromatics, as well as impurities, affect the hardening of the sample at room temperature.

Abstract

Workover and well service activities are routine activities to repair and maintain production wells, such as replacing oil pump equipment and changing well hole reservoir parameters such as drilling and cracking activities This is done to repair and maintain wells so that they can always produce according to the specified potential However, during the work, the production of each well that requires repair must be temporarily stopped until the well is repaired. The length of time a well is not producing depends on the length of the repair of the well. Therefore, drilling performance must be evaluated to avoid delays in well production in the long term. Based on the results of this study, the PDSI# 35.1/IDECO H-35-M rig has a performance level of 88% for 15 days; the performance presentation of the rig is good. In addition, from the results of the NPT using a Pareto diagram, there are several main problems that cause rig performance, namely, waiting for a bright day, waiting for equipment repair time, inspection/safety checklist, and waiting for licensing time.Keywords: Rig Operational Performance.
